Abstract

Curly top symptom development was uniform and no other disease problems were evident in the plot area. The resistant and susceptible checks performed as expected for the visual ratings. Statistically, 12 of the entries contain at least some minor resistance since their visual ratings were significantly lower than those for both susceptible checks. Nine entries from the USDA-ARS Utah sugar beet program that were donated to the NPGS in 1983 (3, 4, 5, 6, 7, 8, 9, 10, and 14) were not significantly different from the resistant check. All nine of these entries were statistically more resistant than both susceptible check lines. An additional two entries from the USDA-ARS Utah sugar beet program (NSL 183366 and NSL 183511) and one Beta vulgaris spp. maritima accession collected by USDA-ARS researchers in Morocco (W6 44508) were statistically more resistant than the susceptible sugar beet check SV2012RR, but had statistically higher curly top ratings than the resistant check. These entries along with entries with similar levels of resistance from prior years evaluations will be retested and, if resistance is confirmed, these lines will be considered for incorporation into the USDA-ARS germplasm improvement program as a source of resistance to BCTV.
